重启apache的时候报错：
/etc/init.d/apache2 restart
[....] Restarting web server: apache2apache2: apr_sockaddr_info_get() failed for (none)
apache2: Could not reliably determine the server's fully qualified domain name, using 127.0.0.1 for ServerName
... waiting apache2: apr_sockaddr_info_get() failed for (none)
apache2: Could not reliably determine the server's fully qualified domain name, using 127.0.0.1 for ServerName
. ok
看到这个(none)，让我想起，我的ssh的登录路径：root@(none):~#
OK，在老鬼的提示上，用hostname函数进行了设置。问题解决：
root@(none):~# hostname
(none)
root@(none):~# hostname neatstudio.com
root@(none):~# hostname
neatstudio.com
